Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31541032, here are decompositions:

11 + 31541021 = 31541032
41 + 31540991 = 31541032
53 + 31540979 = 31541032
71 + 31540961 = 31541032
353 + 31540679 = 31541032
389 + 31540643 = 31541032
401 + 31540631 = 31541032
503 + 31540529 = 31541032

Showing the first eight; more decompositions exist.
